Description
 
 
•  6.35mm TRS Jack Input: This will accept balanced or unbalanced 
signals from a program source or instrument. 
•  6.35mm TRS Jack Thru Output: This balanced output allows for a 
direct output link to an instrument amplifier.  
•  3 Stage input Pad: This 3 stage switch allows 0dB, 20dB or 40dB of 
input attenuation so differing sources can accommodated.  
•  GND Lift Switch: When this switch is in “ground” position pin1 of both 
the input & the output are connected. When this switch is in “lift” 
position these grounds are separated. This switch is used to 
eliminate hum that may be present.

a mixing console, signal processor etc.
